To change the STAC IP password, you must have a PS/2 keyboard and
monitor attached to the STAC mainframe. If a keyboard is not connected to
the mainframe, a reboot will be required after it is attached. You will need
to enter
IP Config Mode
to change this setting. Here’s how:
1) Apply power to the STAC mainframe with a keyboard and monitor at-
tached. Wait for STAC to display the STAC IP interface screen on the moni-
tor.
2) Press
Control-Alt-F3
(simultaneously) on the keyboard. The STAC IP
interface will be replaced by a command line login prompt.
3) Login by typing the user name
root.
Press
Enter
and you will be
prompted for a password. Use the password
comrex
to access the system.
Note this password remains the same even if you change the STAC IP secu-
rity password.
4) At the # prompt, type the word
config
then press
Enter
. This will call
up a text editor to allow you to edit the system configuration file.
5) Use the arrow keys to scroll to the line:
export GUI_PASSWORD=comrex
(The line will display the current password if it has been changed from the
default.)
6) Replace the word
comrex
(or the current password) with the new pass-
word of your choice. Note that the password is case sensitive.
7) Exit the editor by pressing
Esc
. When prompted, choose
save with
changes
and press
Enter
.
8) Recycle power to STAC. The new STAC IP password should be active.
If you are unable to access STAC IP from a remote computer after verifying
all STAC IP configuration settings, you may have a firewall issue blocking
access. STAC IP requires that TCP port 8080 be open on your system to op-
erate correctly. You may need to configure your firewall or router to enable
this port.
